Bitcoin’s 17% crash explained: $88M whale short, tariff shock & more…
Here's a quick rundown of the chaos.
Key takeaways
What just happened in the Bitcoin market?
An anonymous trader made $88 million shorting Bitcoin right before Trump’s surprise tariff announcement.
Why did Bitcoin crash after Trump’s tariff news?
STHs bought near the top, whales dumped, and a perfectly timed short amplified the drop.
An anonymous trader made $88 million by shorting Bitcoin [BTC] just thirty minutes before President Donald Trump’s surprise tariff announcement, causing debate about insider trading.
BTC plunged 17% following the news, aggravated by poorly timed buys from short-term holders (STHs) who snapped up nearly 500 BTC at a record $122,000.
The short that caused manipulation worries
On-chain data reveals that, two days before Trump’s Truth Social post, whales began placing billion-dollar short bets on BTC and Ethereum [ETH].
The motive behind these trades remains unclear, and it’s uncertain whether they originated from the same whale.
Then came the announcement, and markets plunged. BTC dropped 17% in a matter of hours, liquidating over $20 billion in positions. The short doubled right before the official speech.
So was the whale’s monumental short a lucky trade, or a calculated move by someone who knew what was coming?
The real story
The crash was largely a matter of timing – both politically and psychologically.
Retail wallets piled into BTC right at $122K, again.
This is the fourth time in months they’ve bought big at local tops, only to get dumped on by whales. Meanwhile, long-term holders (LTHs) didn’t budge; exchange reserves continued dropping, a sign of steady accumulation.
Political shocks create short-term panic, but it seems it’s always the same players who react.
Will October surprise us all?
So far, we’ve seen panic-selling, political shocks, and classic short-term mistakes, but zooming out reveals something interesting.
October price declines of more than 5% have occurred only four times in the past decade, specifically in 2017, 2018, 2019, and 2021. Each time, Bitcoin rebounded within a week, often with double-digit gains. Economist Timothy Peterson highlighted 7-day recoveries of up to 21% following these rare October dips.
Now, in October 2025, we may be witnessing a similar setup. If the pattern holds, this pullback could be a reset before the next leg upward.
